VENTILATING GLASS. WHTDOW BANE.

Application filed July 19,

To all whom it may concern:

Be it known, that I,Lours LANE, a citizen of the United States of America, and a resi- Cuba, have invented a new and Improved Ventilating Glass Window Pane, of which the following is adescription. 1

My invention relates to ventilating means for windows and particularlyto an improvement whereby the usual solid glass pane in common use in fixed window sashes is provided with an area affording permanent ve'ntilating openings. By fixed window'sashes is meant sashes that do -not open in any way and that'arenot provided with movable ven-v tilation parts or sections to be opened and closed. Infa fixed nonsventilating sash as now employed to a'large extent, especially in steel sashes it'frequent-ly is desirable that minor ventilation of a permanent character he provided at intervalswithout recourse to the expense of regular ventilated or' movable types of sash in'new installations or to the replacement of such existing sash with new ventilating ones. r

i The" general object of the present invention is to provide'means for'such minor ventilation in an inexpensive and practical way and adapted to be glazed in existing pane spaces. The invention is adapted to be employed also in cases where it is necessary to have the minor fixed ventilation as re-' to or as an adjunct of a ferred to auxiliary regular ventilated sash, so that said fixed permanent ventilating means may remain as minor ventsrwhen the regular sash ventilators of the window are closed.

The commonly called pane space or light space in window sashes that are made to be closed are almost uniformly provided with glass receiving rabbetsformed in the sash members surrounding and defining the pane spaces, the saidrabbets being made of a suitablev form to receive the fiat edges of the glass panes which areputtied or otherwise secured in place.

The depth of theglass rabbets referred I to are often relatively shallow as in wooden 1 provide sashes but usually in steel sashes they are relatively deep and occupy in depth the greater portion of the thickness of the sash and it is an object of my invention to embody my fixed ventilating means in such sashes as have the rabbets thereof relatively deep as'in a "steelsash for which purpose I a-metal member to be appliedto 1924- Serial No. 727,052.

the sash V as hereinafter described which, when placed in the bottom rabbet of the sash will afford support for the bottom fixed ventilating glass member.

A further object of the invention is to provide fixed ventilating elements so formed as to present baffle members so arranged as to baflie the entrance of rain through the ventilating openings.

The nature of my invention and its distinguishing features and advantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a front elevation of a portion ofawindow having incorporated therein my improved fixed ventilating elements;

Figure 2 is an enlarged elevation of a fragment of the ventilating means;

Figure 3 is an enlarged horizontal section on the line 3-3, Figure 1;

Figure 4 is an enlarged transverse vertical section on the line 41- 1, Figure 1;

Figure 5 is a fragmentary perspective view showing a corner portion of a plurality of assembled ventilating elements;

Figure 6 is a perspective view of a strip to be employed in the bottom rabbet of the sash for affording support for the lower mo st ventilating element.

In the illustrated example of my invention, the numeral 10 indicates a metal sash frame, the numeral ll'indicating members constituting the cross and vertical muntins of the said sash frame, said members as usual presenting rabb'ets 12 to'receive the glazing. The frame at the four'sides presents flanges 13 in the general plane of the frame adapted to be received in recesses 14: in the wall A.

The-window is represented as having over the major portion of its area plain flat panes 15. In the space defined by certain of the sash members 11, I provide my novel fixed ventilating elements, each designated generallyby the numeral 16, a plurality of which are superposed in said space. Each element 16 is formed of glass and for the-major portion thereof is offset as at 17 to provide an air passage throu h said offset portion. The offset portions width of the elements 16 but terminate short of the sides so that legs 18 are formed. The upper portion 19 of one element 16 extends 1? do not extend the full at the back of the offset portion 17 of the next element 16 above and constitutes a baffie against the entrance of rain through the ventilating passage. The upper edge of the bafiie area 19 of each element 16 except the uppermost one is directed forwardly in the form of a bead 20 to make the bafiie fully effective against the entrance of rain. The top 119 of the uppermost element designated 116 is flat at the extreme upper edge to be received in the top rabbet of the frame 10.

On the several elements 16 except the uppermost one, are outwardly directed rest ledges 21 adjacent the top at each side edge. These rest ledges 21 are offset rearwardly and each presents a seating shoulder 22 to receive a leg 18 of the next element 16 above. The side edges of the element 16 are flat to seat properly in the rabbets 12 and to receive putty B or equivalent glass securing means.- In lieu of the absence of supporting ledges for the legs of the lowermost element 16, I provide a metal strip 23 having the upper portion 219, corresponding in function with the bafiies 19, offset. At the ends the strip 23 i notched to provide end extensions 24 at tie bottom of the strip, which present top rest surfaces 25 for the legs 18 of the lowermost element 16. The strip 23 is received in the bottom rabbet of tie space having the element 16 and is sccured in place by the putty B or equivalent glass securing means.

It will be observed that no operation of opening or closing the ventilating means or other movement of the structure is necessary and that the assemblage thus provided for a fixed ventilating pane structure made of unit elements of uniform shape and size. The bottom strip 23 forms part of the ventilating assemblage and provides the necessary support for the lowermost ventilating element 16. It will be readily seen that the ventilating elements are emplaced in the same simple, cheap and economical way as the ordinary glass panes and as easily emplaced or removed and provides an effective means for affording minor permanent ventilation in unventilated sashes.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims. 7

Having thus described my invention, I claim:
